PURPOSE: An automatic mobile for children is provided to improve the structure and function of a traditional mobile, thereby allowing a user to set an operation time of the mobile and adjust the speed suitable to a baby. CONSTITUTION: The automatic mobile includes a timer(6) that is set to a maximum of 60 minutes, and a small-sized low-speed motor(3) connected to the timer(6) through a wire. When a power is supplied, the motor starts driving at a low speed, and the mobile(5) hung on a shaft(4) of the motor(3) starts moving accordingly. A user sets time by turning a handle(7) in a clockwise direction. When a preset time is over, the motor automatically stops the operation. By installing the automatic mobile 1.5m-2m away from a baby, no harm from electric waves is done to the baby.
